IBM had PL/I compilers for TOS, DOS, and OS on System/360, and for
DOS/VS and OS/VS on System/370. If those weren't full implementations
of the original spec, they were pretty close.
TOS, DOS, and DOS/VS PL/I didn't implement PL/I's multitasking
features (such as TASKs and EVENTs) because those OSes had no
multitasking support.
